Hello,  
  
The systemctl command is provided by the systemd package which is not available on Amazon Linux 2018.03.  
Instead you can use the service command to restart the Apache server.

```
sudo service httpd restart
```

I recommend to check the configuration first.

```
sudo service httpd configtest
```

To use systemd with Amazon Linux, you can use Amazon Linux 2 with provides systemd and the systemctl command .  
  
Thanks,
